ELECTRICALLY-ILLUMINATED SIGN.

Application filed June 25, 1923. ScriaI'No. 647,429.

To all whom it may concern:

Be it known that I, HERMAN A. GRIE- sINcnn, a citizen of the United States and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electrically-Illuminated Signs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being 19 had to the accompanying drawings, and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to improvements in electrically illuminated signs and consists of the matters hereinafter described and more particularly pointed outin the appended claims.

The invention relates especially to what is known as a double face sign with letters or characters on the two opposite faces, and with means within the sign bodyfor illuminating both faces. I The object of the invention is to produce a sign of the kind in which a reflector may be cheaply and eco- 5 nomically provided on the interior of the sign body so. as to act efficiently for both faces of the sign, and wherein the reflector is so constructed that the lamps for the illumination of the sign characters on the opposite faces of the sign may be supported in such manner as to be readily gotten at for removal or renewal.

These and other advantages of the in vention will appear more fully as I pro- L: ceed with my specification.

Referring now to the drawings 1- Fig. 1 is a view representing in perspective a sign embodying the invention with some of the letter plates removed to show the inner construction of the sign.

Fig. 2 is a view representing a horizontal section through the sign in the plane of the lamps which are used for its'illumination.

Fig. 3 is a view representing a vertical section through the sign body in a plane indicated by the line 3-3 of Fig. 2.

Fig. 4 is a perspective view of a part of the reflector plate used in the sign.

The novel improvements comprised in the invention may be embodied in any type of double face sign with transparent, translucent opal glass or other familiar types of sign character plates, depending upon the purpose for which the sign is to be used and the taste or desires of the user of the sign.

each bearing a raised character 13) andl l indicates the stencil plates, there being in this case, a stencil plate for each character. The details of construction in this respect may be of any familiar or well known kind and form no part of the present invention.

15 indicates a partition wall located in a vertical position substantially in the median plane of the sign body. Said partition wall comprises a plurality of vertically disposed panels 16, with the adjacent panels e located in narrowly spaced, vertical planes and connected together by vertical webs 17 extending substantially at right angles to said panels. The panels 16 and webs 17 provide together, a succession of channel-like vertically disposed, open chambers, with the alternate chambers facing in opposite directions.

In the webs 17, and preferably in the horizontal median plane of the sign body, are located in line, a series of holes 18. The webs 17 are made wide enough in a horizontal direction to allow space for holes 18 which are of sufficient diameter to provide support for lamp sockets 19, which are secured therein, in any familiar well known manner. 20 indicates lamps which are severally mounted in the sockets. In each panel 16, in horizontal alignment with the associated lamp 20, is provided an opening 21, substantially of the outline of the lamp bulb.

The opposite faces of the panels 16 are constructed or treated so as to provide bright reflecting surfaces 22, 23, and said surfaces, as will be readily apparent, reinforce by their reflecting character, the light directly transmitted from the lights through the illuminates to some extent, both faces of the sideof the reflectoras the ,said refleqtingsurr face 23.

Maniyfestly, the lamp globes, by reason of ,the: arrangement .descrlbed, areireadilyi gotten at when the sign body is opened, either by removing one of the letter plates and stencils or ,otlierwise,as maybe provided in any ,familiar manner, ;for gaining access to the interior of thesign.

The partition extendspreferablyirom top :to bottomfii --tl1.e sign body and also from end to ,endQof ,the same, being secured in .place at ,its :top and bottomedgesandat its endsin any familiar manner, asby soldering or otherwise. 7

1 claim as my invention:

1'; In an electrically illuminated sign, the combination ,of a sign body Having glass letter plates upon opposite sides thereof, a reflecting partition in said sign :body, mid- WaybetWeen said'letter plates, said partition comprising aplurality of vertically disposed refleeting .panels extending from the topto-thebottom ofthebody and providing a succession of channel-like, vertically d1s-' posed open chambers, and lamp sockets carried :by said partition and {so positioned thereon that the associated lamps are arranged in axial alignment with at least one lamp in each chamber. 1

2. In an electrically illuminated sign, the combinationof a sign body having glass letter plates upon opposite sides thereof, a refiectingnpartition in said sign body midway between said letter plates, said partition comprising apluralityof vertically disposed :refiecting panels, with adjacent panels located in spaced vertical planes and connected'together ,by transiger sely disposed webs providing asuccession of channel-like .vertically disposed open chambers, witlial- .ternate chambers iiacing in opposite direc- -tin,land lamp sockets/carried =bycsaid Webs, ,so that the associated lamps .are arranged ,at leastone in, each ch amber, eachpanelliavingfa n opening thereinbaekof thedamp.

3. reflecting; partition for'ns e in a double face electrically illuminated sign comprising a plurality of vertically. disposed panels with adjacent panelsllocated in narro vly spaced, vei tical planes, said panels being connected together by vertical webs extending substantially v at right angles to said panels, a said ipanelsand webs providing together, a succession of channel-like ,ver- ,tically disposed, ,open chambers, ivith alternate chambers facing in p posite directions.

In testimony that I claim the foregoingas my invention, I affix mysignature this ?21st day, of June, A. D. 192 3.
